<p><span class=rvts10>Troubleshooting</span></p>
<p><br></p>
<p>This section describes potential problems/question that could arise when using FCEUX.</p>
<p><br></p>
<p><span class=rvts12>Slow emulation / Sound crackle</span></p>
<p><br></p>
<p>FCEUX may not run well on slower CPU's.&nbsp; You can improve performance by setting sound to low quality in the<a class=rvts11 href="{57C3F33F-6EEB-4881-8968-B3E0DC60FADD}.htm"> Sound Dialog</a>.&nbsp; In addition, for windowed mode try enabling hardware acceleration in the <a class=rvts11 href="{849BF734-E954-4544-8892-20606DFCF779}.htm">Video config</a> dialog may also help.</p>
<p><br></p>
<p><span class=rvts12>Slow savestates when recording movies</span></p>
<p><br></p>
<p>On slower computers, savestates can be slow with long movies.&nbsp; A small speedup can be done by disabling config &gt; enable &gt; Backup savestates.</p>
<p><br></p>
<p><span class=rvts12>"The colors in game X do not look right"</span></p>
<p><br></p>
<p>FCEUX uses the color palette of the old FCEU / FCEUXD branches.&nbsp; However, FCEUX comes pre-packaged with several additional color palettes.&nbsp; For more information see <a class=rvts11 href="{607BB21A-0839-47E9-AF33-9F631D541D9D}.htm">Palette config</a> and <a class=rvts11 href="{98E9F36B-2822-40C4-B917-B8E0E976C753}.htm">Palette options</a>.</p>
<p><br></p>
<p><br></p>
<p><span class=rvts12>"FCEUX won't open my ROM/File.&nbsp; It let's me select it in the Open File dialog then ignores my selection"</span></p>
<p><br></p>
<p>It maybe be that the filename or pathname includes one or more on ASCII characters.&nbsp; Currently FCEUX does not support Unicode characters.</p>
<p><br></p>
<p><br></p>
<p><span class=rvts12>"I converted a .fcm file to .fm2 but the .fm2 desyncs"</span></p>
<p><br></p>
<p>Depending on what version of FCEU / Game your .fcm was made, there maybe a number of sync issues.&nbsp; These are listed in detail at <a class=rvts11 href="http://tasvideos.org/ConvertFCMtoFM2.html" target="_blank">http://tasvideos.org/ConvertFCMtoFM2.html</a>.</p>
<p><br></p>
<p>In addition, the .fm2 conversion tool has had some issues on certain operating systems including Vista and Mac.</p>
<p><br></p>
<p><br></p>
<p><span class=rvts12>"When I attempt to load a Lua script I get an error / crash"</span></p>
<p><br></p>
<p>Double check you have the Lua .dll files that came packaged with FCEUX 2.1.&nbsp; They must be in the /dll folder from the root directory (where fceux.exe is stored).</p>
<p><br></p>
<p> </p>
<p><span class=rvts12>"Directdraw: Error creating secondary surface"</span></p>
<p><br></p>
<p>Currently this error will happen when attempting to do Full screen mode on Windows Vista.&nbsp; In addition, there has been one reported case of this happening on the 32-bit version of Windows XP.&nbsp; This is a known issue with FCEUX that has not yet been resolved.</p>
<p><br></p>
<p><br></p>
<p><span class=rvts12>"Can't find FDS Bios image when I attempt to load a .fds game!"</span></p>
<p><br></p>
<p>FCEUX requires the FDS Bios to be named disksys.rom.&nbsp; It must be located in the root directory (where fceux.exe is stored) or in the folder of the FDS Directory override (see <a class=rvts11 href="{D6DDB3DB-500D-4DCE-8D48-10A67F896057}.htm">Directory overrides</a>).</p>
<p><br></p>
<p>In addition, there are some bad versions of disksys.rom.&nbsp; The one FDS requires is 8192 bytes.</p>
<p><br></p>
<p><br></p>
<p><span class=rvts12>"How can I use Netplay / Where can I get FCEU Server?"</span></p>
<p><br></p>
<p>Currently FCEUX is not compatible with the FCEU-server code.&nbsp; This is a known issue and will be resolved in a future release.</p>
<p><br></p>
<p><br></p>
<p><span class=rvts12>"I have a Game Genie rom, how can I use it with FCEUX?" </span></p>
<p><br></p>
<p>While FCEUX has a <a class=rvts11 href="{ACA99B5B-9CA3-4E69-B7F7-106D70CF76BF}.htm">Game Genie code converter</a>, you can also use game genie codes with the game genie rom.&nbsp; It must be named gg.rom and be placed in the root directory (where fceux.exe is stored).&nbsp; You must also check NES &gt; Game Genie in the main menu.</p>
